With mechanical engraving, the process occurs using a sharply sharpened rotating cutter, which cuts the material. In the case of laser engraving (more popular method), everything is a bit more complicated. But despite the differences in the technology used, and the one, and the other technique can be used for the manufacture of various products from polyethylene or for 3D printing and color printing. Let's say it can be a number for wardrobe or topical menus today for cafes and restaurants. Manufacturing this product for a long time, the company "Universal Advertising" - www.universal-reklama.ru.
Features of laser plastic engraving
The radiation of the laser changes the color or the structure of the plastic, or removes the surface layer from the material. Due to the fact that the thickness of the evaporating layer is minimal, the surface relief gets an amazing look. Images are characterized by high resistance, quality and resolution. Other methods of processing such results cannot be provided.Laser engraving plastic happens:
- Vector. Images are applied with thin lines;
- raster. The result is photographic halftone images.
Adjusting the depth of exposure to the laser beam, it is possible to obtain bulk laser engraving. Inscriptions and drawings on plastic can be any.
How to choose plastic for engraving?
To apply images, you must select a multilayer special material. Plastic layers are different in color. Laser technique evaporates the top layer, opening another. The thickness of the upper layer is usually 0.05-0.08 mm. The color of the bottom is usually a contrast. The surface of the plastic can be a glossy or matte.
Subtleties and important points
And mechanical, and laser engraving make it possible to manufacture single and small batches of products. Due to the fact that the consumables (matrices, printed forms, etc.) are not available, clients need to pay only the process and work of the operator.

If you need to get a big batch of complex products, choose laser engraving. The rate of application is really high, and the pictures and texts themselves can have any kind, including volumetric.
The types of plastic for engraving are also different. In addition to metallized material, they all usually have ultraviolet protection. Engraved images are not terrible climatic effects. And therefore, products with them can be used on the street.
